Stygiomedusa gigantea, commonly known as the giant phantom jelly, is the only species in the monotypic genus of deep sea jellyfish, Stygiomedusa. It is in the Ulmaridae family. With only around 110 sightings in 110 years, it is a jellyfish that is rarely seen, but believed to be widespread throughout the world, with the exception of the Arctic Ocean. The bell of this deep-sea denizen is more than one meter (3.3 feet) across and trails four ribbon-like oral (or mouth) arms that can grow to more than 10 meters (33 feet) in length.

The giant phantom jelly occurs all around the world with the exception of the Arctic Ocean. They are typically found 61°N–75°S and 135°W–153°E. In areas of high latitude in the Southern ocean, the depth at which the species may be found are at the mesopelagic and epipelagic levels.

Known to be one of the largest invertebrate predators in the deep sea, the giant phantom jellyfish's typical prey consists of plankton and small fish. The S. gigantea tends to be more dominant in locations with a low productivity system, which in turn deters other predatory organisms, like fish, to high productivity systems (coastal, upwelling zones). However, the jellyfish remains an important predator for the deep sea, often competing with squids and whales.

Evidence has been collected to support the first-ever documented symbiotic relationship for an ophidiiform fish, Thalassobathia pelagica. Scientists have observed that the large umbrella-shaped bell of S. gigantea provides food and shelter for T. pelagica, while the fish aids the giant phantom jelly by removing parasites. The S. gigantea's jelly providing shelter for T. pelagica is essential for the fish, considering the lack of shelter resources at such extreme ocean depths. Studies to further support this symbiotic relationship have shown that the two species reassociate with one another even if separated. It was inferred that T. pelagica is able to find its way back to the giant phantom jelly due to neuromasts that increase the sensitivity of low-frequency water movements which the bell of the jellyfish emits.

Instead of alternating between their medusa and polyp stages like most jellyfish, the giant phantom jelly covers their young in their huge bell. As a result, they "give birth" to young that are already at their medusa stage. It is inferred that reproduction of S. gigantea is continuous with one parent estimated to produce fifty to one hundred medusa.

Lethocerus americanus, sometimes called the electric light bug, toe biter or fish killer, is a giant water bug in the family Belostomatidae, native to southern Canada and the United States (north of 35°N; other Lethocerus species are found southwards). It typically has a length around 5–6 cm (2.0–2.4 in). It was originally classified as a species in genus Belostoma. This flattened oval-shaped, brownish insect can get up to 6 cm long. Its front legs are well-developed and adapted to grasping prey, while its flattened back legs are used for swimming.

As its name implies, the giant water bug is found in and around aquatic habitats such as ponds, creeks and streams, marshes, and lake edges. It is a strong flier, and is attracted to lights at night. Giant water bugs are common and found throughout most of North America. They are active from spring to fall, and adults overwinter in mud in aquatic habitats.

This insect is a predator, as indicated by its other common common names, 'toe biter' and 'fish killer'. It eats other aquatic invertebrates, small fish, and amphibians — such as this Pacific chorus frog. Like other members of Family Belostomatidae, the giant water bug may bite humans when disturbed. Bites can be very painful and may even cause permanent damage: upon biting prey the insect injects digestive enzymes to liquefy tissue that can then be sucked out. On humans this can produce a painful lesion.

Lethocerus americanus lays their eggs above water on vegetation, where the male guards it from females that would eat the eggs so the male will bear her offspring instead. Some other giant water bug species lay their eggs on the backs of males. The male then carries the eggs around until they hatch. Adults live about one year.
